OK you asked me where lava comes from. Lets say I answer and say I don't know. We will assume for the time being that all the books I have read by people who have spent their lives extensively studying volcanoes in various parts of the world and all the documentaries I have seen and the geology teacher I had for two years are all lying to me. I don't consider any of those being part of any 'authority' as you call it. Just individuals who are keen to learn about the world and the environment they live in.
How do you propose I find out where lava comes from?
You're missing my point.
You have every right to believe what you're told. You have every right to believe all you read. And you have every right to feel your absorbed to mind answers are your very own understanding of what you believe of those who study whatever it is that is passed to you through books or verbal...etc.
There's only two ways to find the truth of something.
1.....To be told something from people who physically know the truth according to their own scientific endeavours.
Basically, it means you have the ability to go and check it out without being impeded.
2. You find out for yourself and verify, physically.
Anything else is acceptance of stories told if you are not allowed access to the workings.
Basically you believe on face value, which isn't a bad thing.
After all we basically go with the flow of life which includes lots of face value acceptance...including myself.
However, I have many things which I do not accept and I question them and come to my own musings on potential alternatives....most of which I could not definitively prove to be factual due to the physical nature of finding out would be extremely difficult to almost impossible.....and likely, impossible in some aspects.
So, it comes down to best guesswork from my side and from your side it comes down to your best belief's from what you're told....especially with what we are debating.
My point is very simple.
If you want to try and understand an alternative musing/hypothesis/theory or whatever you want to call it....then you can't tangle it with what you already believe.
You have to place whatever you believe to the side and try and see the alternative, even if you 100% disagree with every aspect of it.
If you don't or can't follow it, then you try a better way and try and coax me into providing better analogies and such.
If you want me to put experiments out for you to do and for you to follow,, then ask but don't expect me to put videos up of me doing them.
I'm just trying to be as honest as I can.
